Abstract: <P>PROBLEM TO BE SOLVED: To suppress power consumption of a needless slave base station in a group base station configuration composed of a master base station and slave base stations.  <P>SOLUTION: Usually, only a master base station 1 operates, and slave base stations 4 are shut down or in a standby state. The slave base stations transit to an operational state one by one, when traffic increases and the number of remaining resources for the whole group base station reaches an established value. In addition, a call is assigned sequentially to a slave base station having high priority, when slave base stations are in the operational state. When traffic decreases and the established number of remaining resources is secured, an unused slave base station transits to a shut-down or standby state. Consequently, useless power consumption is reduced.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Filed: 2004-06-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide an injector reducing a bound of a valve member in opening a valve, with simple structure without causing an increase in the number of parts.  <P>SOLUTION: A deforming member 70 is installed between a seat face part 53 of a movable core 50 and a spring 18. When a needle 30 collides with a nozzle body, the movement of the needle 30 and the movable core 50 toward a fixed core 43 deforms the deforming member 70. Energy for moving the needle 30 and the movable core 50 toward the fixed core 43 is thereby converted into thermal energy by the deformation of the deforming member 70. As a result, the bound of the integrated needle 30 and movable core 50 is reduced when the needle 30 collides with the nozzle body. The bound of the needle 30 can thereby be reduced with simple structure without causing an increase in the number of parts, and uncontrollable fuel injection from a nozzle hole 25 is reduced.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
